Object: Connect four of your checkers in a row while preventing your opponent from doing the same. But, look out — your opponent can sneak up on you and win the game!
Connect Four (also known as Captain’s Mistress, Four Up, Plot Four, Find Four, Four in a Row, Four in a Line and Gravitrips (in Soviet Union)) is a two-player connection game in which the players first choose a color and then take turns dropping colored discs from the top into a seven-column, six-row vertically suspended grid. The pieces fall straight down, occupying the next available space within the column. The objective of the game is to be the first to form a horizontal, vertical, or diagonal line of four of one’s own discs. Connect Four is a solved game. The first player can always win by playing the right moves.
The first player begins by dropping one of his/her discs into the center column of the game board. The two players then alternate turns dropping one of their discs at a time into an unfilled column until one player achieves four in a row — either horizontally, vertically or diagonally; the player that does so wins the game. However, if the game board fills up before either player achieves four in a row, then the game is a draw.
